Window box planters have been making appearances on houses since ancient times. The Romans used terracotta versions for growing foods and plants for medicines. As window boxes made their way through Europe, they used such materials as wire & hay, wrought iron and tin. The modern versions seen on homes today showcase beautiful blooms that delight the eye.
Consider these guidelines when adding window boxes to your home.
Your window box should match the length of your existing window and should not exceed 25% of your windows height. Examine the area and make sure it can support the box you choose plus the weight of the dirt and flowers. Consider the amount of sunlight this area receives, this will determine the type of flowers you plant.
Window boxes come in a variety of materials, each with pros and cons to take into consideration.
Metal - strong and durable, but can dent easily and rust.
Fiberglass - does not rot and can be painted to match your home, but is pricey.
Wood – easy to customize, but is susceptible to rot and insect damage.
Terracotta – readily available, not a good choice for colder climates.
Plastic – lightweight and inexpensive, less durable.

When you choose your flowers, keep in mind the amount of sunlight they will be receiving. Start with younger plants that will root well. Zinnias and marigolds are very tolerant of the heat, while impatients and fuschia need shade. Pansies and petunias are a great all around choice. A composition of flowers or vines that trail over the edge makes for a pleasing display. Choose a potting mix that contains peat or other ingredients that help to maintain moisture. Arrange your plants 2 to 5 inches apart so there is room for growth. Water daily and prune plants as necessary.
An herb garden is a fun idea for a window near the kitchen. Fill it with herbs like rosemary, oregano, thyme or mini pepper plants that can be used in cooking over the summer.
